High-Resolution Spectroscopic Study of the (310) Local Mode Combination Band System of AsH3
The high-resolution spectra of AsH3 in the 8130-8340 cm-1 region, which were assigned to the (310;A1), and (310;E1), and the (310;E2) local mode combination bands, have been recorded at a resolution of 0.01 cm-1 and rotationally analyzed. The spectroscopic parameters were obtained by least-squares fitting. The rotational energy levels were fitted for the (310;A1) state (21 levels in all) up to J = 5, for the (310;E2) state (43 levels in all) up to J = 7, and for the (310;E1) state (43 levels in all) up to J = 5. The complication of the rotational structure indicates rotational perturbation. Copyright 1998 Academic Press. Copyright 1998Academic Press
